In the context of PHP development, what role does proper variable initialization play in preventing common programming mistakes?

Proper variable initialization is crucial in preventing common programming mistakes such as using undefined variables or unexpected behavior due to uninitialized values. By initializing variables with default values or appropriate values before using them, you can ensure that your code functions as intended and avoid errors.

// Initializing variables to prevent common programming mistakes
$number = 0;
$name = "";
$isActive = false;

// Now you can safely use these variables in your code without worrying about uninitialized values
